Graphing transformations: y=3 f(-x) (picture below, all the way at the bottom)

I know that I'm suppose to flip it over the y-axis, but I don't understand the stretching part.

OpenStudy (anonymous):

Are you told that f(x) = f(-x) in this problem? What else are you told besides the graph you posted?

OpenStudy (anonymous):

stretch by 3(simply multiply each point you graphed by 3, that will stretch your graph

OpenStudy (anonymous):

That's all I'm told, oh and this 0<=x<=4

OpenStudy (anonymous):

You flip over the y-axis only if you were told that either f(x) = f(-x), or that f is an even function, or it is symmetric about the y-axis.

OpenStudy (anonymous):

You need more info, because you dont know if f(x) = f(-x).

OpenStudy (anonymous):

That is, in the graph you provided, f(2) = 1. We know nothing about f(-2).

OpenStudy (anonymous):

Unless something in the directions alludes to f(-x).

OpenStudy (anonymous):

We could graph 3f(x). Thats not a problem.
